Description and analysis of double flange limit expansion joint

Double flange limit expansion joint is a bearing end cap on the pressure vessel, which is an important bearing force prefabricated component of the pressure vessel. The role played is the role of confinement. One is made into the tank-shaped pressure vessel of the upper and lower bottom, the second is the pipeline to the head, not ready to fill and then widen forward, double flange limit expansion joint in the tap water pipe with welding method of confinement. Double flange limit expansion joint application is very sexual, not environmental pollution. In the current producers can also be improved, without improving the machinery and equipment, cost-effective, suitable for large-scale production and manufacturing. Double flange limit expansion joint machine and equipment corrosion problem is a key element of the development trend of chemical machinery and equipment, this problem can not be dealt with in the short term, therefore, to improve the anti-corrosion characteristics of chemical machinery and equipment, improve the anti-corrosion characteristics of all normal applications in chemical machinery and equipment has a key practical significance. In order to improve the service life of petrochemical equipment, multi-functional anti-corrosion material is one of the better methods.
